ارتباط نسبت HDL/TG به عنوان نشانگر مقاومت به انسولین با سطوح مختلف قند خون ناشتا

ABSTRACT

       Background and Objective: The association of Triglyceride/High Density Lipoprotein-Cholesterol (TG/HDL-C) ratio with fasting serum insulin, which is an alternative method of insulin resistance (IR) measurement, is well-recognized. Thus, the measurement of TG/HDL-C ratio is useful to determine both IR and dyslipidemia, which itself is a characteristic of individuals with IR. Therefore, this study aimed to investigate the relationship between TG/HDL ratio as an indicator of IR, with different fasting blood glucose levels.

      Methods: This case-control study was performed on 343 volunteers with no history of diabetes or use of blood glucose-lowering medications and fasting blood sugar (FBS) levels of less than 126 mg/dl. After sampling, the subjects were divided into three groups based on their FBS level. First group included healthy subjects with FBS of less than 100 mg/dl. Second group consisted of subjects with impaired fasting glucose (IFG) and FBS of 110-100 mg/dl and a third group including those with impaired glucose tolerance (IGT) and FBS of 110-125 mg/dl.

       Results: The amount of TG/HDL-C ratio was 3.8 ± ۲٫۸, ۴٫۰ ± ۲٫۱ and 5.4 ± ۳٫۸ for the healthy group, individuals with IFG and IGT, respectively. The TG/HDL index was significantly different among the tested groups with no significant difference between healthy subjects and subjects with IFG. Moreover, there was a statistically significant difference between the IGT and IFG groups with healthy individuals.

       Conclusion: Considering the significant increase of the TG/HDL ratio in groups with impaired glucose, using this index can be helpful in evaluation of glycemic disorder.
